To all 'whom 'Zt may concern: l

-Be it nown that I, EDWARD A. FRIEsn,-a citiz of the United-States, residing at Birn' gham, in the 4county of Jefferson and tate of Alabama', have invented new and tents of a fluid receptacle which'fluid will be contained therein.

positivelyl discharged from thev bottom of. the receptacle, to provide means to keep the discharge pipe lled at all times, and to provide a drain for the discharge nozzle'which will return the fluid either to theinterior of. the receptacle' or to the bottom of the-fluid It is also an objectpf this invention to in clude a stroke regulating device for operating the discharge mechanism, and 'also to provide a series o f interlocking covers when the invention is'employed in connection with` jars.

The syrupbeing taken from the 'bottom of the jar at each discharge it dis4 penses the oldest, coldest, heaviest, thicker syrup first, thereby rendering it impossible for the syrup to crystallize. As the measuring chamber is lled from the bottom every downward stroke of the piston will {dis- As thev discharge pipe isA lprovided lwith al check valve at the bottom, the pipe will 'always` be -lilled with syrup. up to the top of the- Jar regardless ofthe amount of syrupin the ]ar, and therefore the same' amount of syrup'wllv be actually dispensed at each operation. return pipe leading from the nozzle tothe l bottom of the measuring chamber uponv the upward stroke of the'piston will draw back into the measuring chamberall of the syrup.

rtliatfminor. detail changes may be made The piston s trokeVregulati-ng device is so construct-ed that no foreign matter can enter within the receptacle through the sleeve sun, rounding the piston rod where it passes While the. preferred ,forms of this inven-l tiouare illustrated upon the accompanying i sheet ofdrawing,' yet .it is to' be understood 1 Iwithout Adeparting from' the scope thereof.

Figure 1 is a' view in vertical section taken through one form lof this invention as' 'applied to a soda water fountain. Fig. 2 is an enlarged front view lpartly in section 'of a modified vform of the invention illustrating the' discharge and return pipes, and discharge end of nozzle with parts bro-ken away. Fig. 3 isa lview in perspective illus-v trating the interlocking of the covers with the front flange broke-n away. The drawings illustrate-this invention as appliedto'avsyrup receptacle in a soda founf tain in which there is a'space between the dispensing slab -1 and the vertical partition 2 for ythe insertion and removal of the syrup the jar 3 4engaging'portions of the slab l and `vertical partition 2 and this cover 5 supports the 'pumping mechanism.

Lreceptacle 3. 'A cover l5 is supported over While it .is preferable to form the syrup* l receptacle with a depressed portion adapted j y.

to receive the measuring chamber as illus# trated, yet it is 'not essential to this inventim).

The' measuring chamber 6 is provided with a discharge-pipe 7 leading from v the fron'tfthereof to .the nozzle 8, whichis preferably screw threaded to the cover 5.

T e bottom Aof the measuring chamberv is y I su ported by legs 9above the bottom ofthe syriip receptacle 3, and is provided with a depression 10, which rests upon the bottomr ofthe receptacle?) and this depression is lin communication with the bottom ofthe measuring chamber Gand'l the bottom of the dis'- eharge pipe 7, so that the liquid in the meas uring chamber will pass therefrom intothe I.bottom of the discharge pipe 7. A check` valve is provided preferably alt the bottom ofthe dischargepipe 7 vwhich will allow the Huid` to ass therethrough but not return;

This chec valve .-12is preferably of the ball and socket type. ...A flap valve 13 is preferablyfmounted at the top of the dischargel pipe-H7 allowing thefluid to pass theref' Y through into the-dischargenozzleand ar,-

ranged in an inclined position wheny closed to direct the returning syrup at the end of the discharge into a return pipe 14 leading to the interior of the receptacle 3. lVhile the fluid is being discharged the flap valve 13 will close the opening into the return pipe 1st and thereby positively dispensethe contents of the measuring chamber at eacli operation of the piston. Thespring 13b will positively return the valve 13 to'the inclined position over the discharge pipe 7 after each operation. The bottom of the measuring chamber G is -provided'with an intake valve 16 upon the bottom and this valve 16 is adapted to be received in a recessed portion', so that the piston y17 may come flush with the bottom ot' the-measuring chamber. On the under side ot' the intake valve a strainer ,1S is provided which may be a perforated plateora wire mesh, and will prevent foreign substances from being dispensed with the syrup. A piston rod 19 is provided with anadj ustable stroke limiting device, which will enable the operator to dispense a given quantity of syrup at each operation. This stroke limiting device comprises a tubular member 20, preferably screw threaded to the upper end of the piston rod 19. A sleeve 21 is secured to the cover 5 and through this sleeve the tubular member 20 passes. The tubular member 2O is -provided'at the exterior end with a cap 22 upon which-may be displayed a syrup label 23. A cap sleeve 24 depends from the under side of the cap 22 and is preferably screw threaded thereto, said sleeve being of sufficient diameter to pass snugly over the cover sleeve 31, and tl ese sleeves 31 and 24 are of such lengths tliatupon the utmost v.downward stroke of the piston rod 19, the bottom of the cap Sleeve 24 will engage the plate 25 secured to the cover 5, and yet upon the end of the upward stroke the bottom of sleeve 24 will overlap the top'of. sleeve 21. Sleeve 24 isf provided with an adjustable ring 26 which is preferably screw threaded on the interior and in engagement 4with asimilarly screw threaded portion upon the bottom of the cap sleeve 24. The top of the ring `26 is preferably provided with an internal flange adapted to engage with an external flange upon a retaining ring 27, which is provided with a set screw adapted to engage the cap sleeve'2fl; and retain the retaining ring in position thereon. The piston is retained at the uppermost end of its stroke by a spring 28 upon the interior of the tubular member 20 which spring is in engagement with the under side of the cap 22.01' syrup label carried thereby and is provided with a securing means at the bottom. The sides of the tubular member 20 arevprovided with slots `dia metrically opposite 'each other and a pin or bolt 29 is passed through 4these slots and in engagement 'with depending members upon pending flanges.

the cover 5. The pin 2t) engages lthe. bottom of the spring and holds it in position.

By loosening the set screw upon tht` retaining ring 27, the ring 2G may be adjusted upon the cap sleeve to the position required and upon screwing up the set. screw on the retaining ring 27 it will be retained in this position, so that upon the downward stroke of the piston the lower portion of the ring' 26 will engage the plate 25 and .determine the amount of syrup at each discharge.

Syrup jars are usually arranged ,side by side in soda fountains, and in accordanpe with this invention the cover 5 is provided with means interlocking with the adjacent covers'and with means interlocking with a portion ofthe slab 1 and vertical partition 2 to preventany foreign substance entering between the covers or between the cover and supporting means and gaining access to the interior of the syrup receptacles. end each cover is provided with 'tour deon one` side is perfectly straight. pending flange 31 on the other sid 1s bent back upon itself, as clearly shown in Fig 3 so that it will enafre and interlock with a c a 1 1. the Straightlange 30 upon tue adjacent cover. It is preferable that -au angle iron' 32 be secured to the underside otl the dispensing slab 1 to support the covers 5 and the angle in this iron extends a suliicicnt distance beyond the slab 1 to allow the rear flange 33 to engage thereon. The side flanges 30 and 31 are cut away at -B-l :to allow for this angle 32.' rl`he side flanges 30 and 31 are terminated short of the front edge of the cover 5 and lit snugly against the inner side ofthe top of the vertical partition 2. A depending flange or rib loprojects downward from the front of the cover 5 and the vertical partition -2 is provided 'with a depression or groove to receive the' flange 35.\ The back of the cov-er 5 may be 'supported'in the same manner upon the slab 1, if desired, without altering the construction of the back flange.-

In Fig. 2 another form is disclosed. In this form a return pipe 13a' is shown leading from the nozzle S to theibottom of the dispensing chamber 6. This return pipe 13a is provided with a check valve 36 at the bottom *thereof which will prevent the discharge lof 'syrup therethrough from the measuring chamberupon thedescentof the piston. The

To this The 'depending flange 30' The de@ u per end of the' discharge pipe 7 is provided with a flap valve 37 allowing a diS- charge of the syrup therethrough and is so weighted'that it will close .in an inclined position which will direct the returning syrup to the return pipe 13. The end of the` discharge nozzle, as shownl in the broken away portions-of Fig. 27 is provided with a perforated" closure 3S through which the syrup may be'discharged, but which will "35 therethrough;
